Description

HYDRAULIC ACTUATOR AT DISTANCE FROM FLUXOMETERS FOR MINGITORIES AND RETREATS FIELD OF THE INVENTION The present invention is related to the manufacturing industry of bathroom accessories, such as keys, fluxometers, bathroom furniture, among others. More specifically, it is related to the bathroom safety accessory industry.

BACKGROUND OF THE INVENTION There are endless situations in which it is required that valves and fluxometers are operated by means of actuators with only one part exposed to the user, that this actuator has little movement when operated and that the key or flushometer to be actuated. find out of the user's access.

The flushometer is an automatic valve, which doses and controls in a single operation the water required by the sanitary furniture to clean it, this does not initially require to correctly interpret the correlation of the systems of the water flow opening and closing cycle. of the same.

In US patent 6,018,827, in the background of the invention, several circumstances are mentioned in which the characteristics indicated in the previous paragraph are required. It also mentions and discloses a structure to solve the problems presented in the circumstances already indicated. This patent is attached in full to understand the novelty that we propose in the present application.

In this US patent, products that perform the same function and use different means to achieve the objective are disnated. These products present solutions using hydraulic actuators, or use Electro mechanical solutions operated through push buttons.

A sanitary cabinet for prisons consists of a cabinet with integrated sink and rate, an electrically or mechanically operated valve, associated with an element for regulating the flow of water, a control associated with the valve to control the operation of the same, and an asly button type "push" cooperate with the control. The push-type button has an axially movable piston, a mobile element that supplies a signal, an elastic member disposed on a slidable clutch that engages the signal-providing element to selectively position and maintain the signal-supplying element in two positions . The push type button is associated with the Control, which generates a signal directed to the control and therefore causes a control signal to the valve There are basically two state-of-the-art systems used to meet the operating requirements of a urinal flushometer or toilet. One of these is the hydraulic system, in which the pressure of the water supplied to the hydraulic network of a construction is used to operate a water outlet device, be it a flushometer, or a hydraulic valve.

The other system is an electronic system, in which various electronic elements are used to operate the water outlet controls.

One or the other has advantages and disadvantages and in each case the best one should be evaluated. For example, the hydraulic system has the advantage of not requiring batteries or connection to the electrical network.

The product that is intended to be protected by this is a hydraulic drive equipment to be used in furniture for bathroom facilities in prison systems. Effectively, this equipment is already in the public domain, but nevertheless, these have construction characteristics that make it difficult to manufacture, maintain and reduce its useful life.

There is the Sloam ™ brand system, in several models. It is an element that can carry out the transmission of movement for the discharge system of a flushometer remotely (hydraulic system).

It is a control valve system that works in the following way, a bolt, when activated by pressing it, compresses a spring and displaces seals to allow the passage of water through the internal area of the valve body. The flow of water is then conducted to the actuator and activate one of its bolts as a result of the force exerted by the water at different pressures. This activated actuator bolt displaces the bolt of the fluxometer in pendulum form and initiates the water quantity flow determined by the design of the said fluxometer.

In other words, the system of the actuating mechanism of one of the systems of the state of the art is operated by the passage of water that allowed the control valve. It contains a et, bolt and spring that yields to the water pressure to move the actuator bolt to the front and actuate the telescopic bolt of the diaphragm. The above allows the discharge of water in predetermined time and quantity. Which has an open and closed position cycle regarding the activation pin by the pressure exerted by the water.

The control valve is very complex in its operation, machinability and assembly. It must be hermetic in the body, it is contemplated so that the water passes inside for its activation. Some of these comprise up to 16 pieces and the fastening system for the hoses is mechanically, that is, it is connected to the nipple and the closure is ensured with the nut.

The actuators of the state of the art have the problem of often being clogged with the impurities of the water, the orifices for the flow are small and can reach up to 12 pieces.

OBJECTIVES OF THE INVENTION The present invention has the objective of making possible a device for the remote control of fluxometers that does not require electrical energy for its operation and to be of simple manufacture and assembly, thereby reducing the production costs.

Another objective is to achieve an actuator and a control valve with a filter system that achieves a long service life around 7 years and with a reduced number of corrective and preventive maintenance.

And all those objectives and advantages that will become apparent with the reading of the present description, accompanied by the drawings that are non-limitative illustrative purposes, are annexed in the present description.

A detailed description of the present invention will be made below DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hydraulic device for remote actuator of flushometers for urinals and lavatories. This device has two main elements, the actuator that displaces the stem of the flushometer and the control valve that allows the passage of a water flow, which leaves the same flushometer, to the actuator to be able to move a piston with a piston rod. one of its ends and to be able to displace the diaphragm bolt of the fluxometer.

As it could be shown in the previous chapters, the complexity of some actuators and control valves of the state of the art, is the origin of problems of manufacture, production costs, and excessive corrective and preventive maintenance.

Figure 1, which illustrates in longitudinal section a control valve of the state of the art, comprises the parts that make possible its operation in the following way: the control valve system works in the following way: the bolt (84) is activates by pressing it forward, which displaces the seals (78, 80) and compresses the spring (82) to allow water to pass through the internal area (74, 76) of the control valve body (70, 72) which aims to reach the actuator and activate the bolt as a consequence of the force exerted by the water at different pressures, (38) water intake, (40) water outlet. The above generates an opening and closing cycle (time and discharge of the control valve.

Figure 2, which illustrates, also in longitudinal section, a state-of-the-art actuator, formed by a housing delimiting, at one of its ends, a chamber where a piston 21 moves on one of its faces and comprises a rod 24 and a spring 23 surrounding this rod. At the opposite end, the housing comprises a body 22 with two veins, one axial, for the water outlet 26, and the other longitudinal, for the entrance of the water flow 25 that will drive the piston 21 to move piston and rod to drive the diaphragm pin 29 of the flushometer.

The housing is fixed to the flushometer by means of a nut 27. Said housing has a perimeter entrance consisting of a perimetral groove, where the water intake 28 will always coincide through the flushometer, and on the other side the vein that opens into the flushometer. the water outlet 26.

Figure 3 shows in longitudinal section the actuator object of the present invention. In this actuator, the actuating rod 24, the diaphragm pin 29 of the actuator of the prior art is maintained. However, for the purpose of assembly and maintenance, the main body of the actuator is formed by 3 sections. The first section is a body 30 that will form the chamber where the piston 21 is to be displaced, this body 30, at the inner end has a threaded cap 31, with a bolster to allow sealed displacement of the rod 24.

To the outside, there is a second body 32, which could be designated as copy. The outer end of the first body, on its outer face, is surrounded by the inner end, on its inner face, of the second body and form the conduit that will carry the water of the admission through the flow meter, to the third body 33. In this conduit will be located the filter that will allow a better functioning of the set.

It is in the third body where the two conduits, the inlet and the outlet, of the flow going to and from the control valve will be located.

This structure is very easy to disassemble and assemble and easy to manufacture Figure 4 shows in longitudinal section the control valve object of the present invention. As can be appreciated, this valve is formed by a lower body 40 that delimits a chamber where a check valve 41 is housed, has a threaded opening 42, at its lower end, to be connected to the outlet of the actuator; laterally, near its upper end, it has another opening 43 with a thread where it is connected to the conduit that arrives at the entrance of the actuator.

On the upper side of the lower body, there is a hole with internal thread, where a kind of copy 45 is screwed, with a perimetral groove on its upper face, where a spring 46 is going to settle, which will make a button 47, is moved upwards, by dragging and pushing a bolt 44. In the upper part, on the outer face, said copy 45 comprises an external thread to be coupled to the internal thread of the escutcheon 48. Said escutcheon has an external thread for, for means of a nut to fix the control valve to any wall of any piece of furniture, having only one hole to house the control valve.
